I have a 32 inch Toshiba TV (CX32D60) vintage 1994. It developed a problem

If You can solder and have access to capacitors then this is likely
fixable. 99% of the time what you describe is due to one 20 cent cap!

don't bother with ESR meters unless you plan on fixing tvs regularly,.
just change the caps near the frame /vertical IC. there aren't many
and they arent expensive. look for a small ish IC, usually on a metal
heat sink with anything from 6 legs. ( older sets used a pair of
transistors but this is doubtful in your case).

tip: if the ic is labelled say IC 401, then change all the nearby
caps similarly labelled , eg c405 c408 etc etc. do them one at a time
so you don't mix them up. good luck
